GeForce RTX 3070 vs GeForce GTX 1660 SUPER: In-Depth Breakdown
Performance: GeForce RTX 3070 vs GeForce GTX 1660 SUPER
The GeForce RTX 3070 is dramatically faster, around 145% ahead of the GeForce GTX 1660 SUPER. That gap is enough to move it up a tier: the GeForce RTX 3070 is comfortable at 1440p, while the GeForce GTX 1660 SUPER is better matched to entry-level 1080p. The GeForce RTX 3070 packs 5,888 CUDA cores versus 1,408 on the GeForce GTX 1660 SUPER.
Price & Value
Pricing has the GeForce GTX 1660 SUPER at $159 EUR, $341 EUR under the GeForce RTX 3070's $500 EUR. Despite being slower, the GeForce GTX 1660 SUPER offers the better performance-per-dollar (~28% better value), so budget-focused buyers should weigh it carefully. The GeForce GTX 1660 SUPER is trading below its $229 EUR MSRP — a genuine deal.
Power & Efficiency
At 125W vs 220W, the GeForce GTX 1660 SUPER is the gentler load on your system. The GeForce RTX 3070's extra power draw buys more performance per watt, not just more heat — worth it if your PSU has the headroom. Its more modern Ampere architecture on a Samsung 8nm process is part of why it does more with each watt.
VRAM & Future-Proofing
The GeForce RTX 3070 carries 8GB versus 6GB on the GeForce GTX 1660 SUPER. The extra 2GB helps at 4K, with high-resolution texture packs, and for content-creation or local-AI workloads that exhaust smaller buffers. The GeForce RTX 3070's memory is also faster — 448 GB/s versus 336 GB/s (256-bit vs 192-bit bus) — which helps feed the GPU at 4K and with heavy textures.
Which should you buy: GeForce GTX 1660 SUPER or GeForce RTX 3070?
Choose the GeForce RTX 3070 if you want the most performance and can absorb the higher price. If you're optimizing for value, the GeForce GTX 1660 SUPER stretches your money further for only slightly lower performance.
